Matthew Poole and continuators on Deuteronomy 32:28

28 For they are a nation void of counsel , neither is there any understanding in them.

Either 1. the enemies last mentioned, who are foolish people, and therefore make so false and foolish a judgment upon things. Or rather 2. the Israelites themselves, of whom he speaks both in the foregoing ver. 26. and in the whole foregoing chapter, and in the next v. 29. and afterwards.

That have not wisdom to direct themselves, nor discretion to desire and receive counsel from others, but rashly and madly go on in those courses which will certainly ruine them.
